. SPECIHCATIOH forming part of Letters rai-.ent No. 603,483, dated May s, 1898.

To @ZZ 'whom it may concern,.-

Beit known that I, TONEY CHARLES HEFEL,

a citizen of the United States, residing at Muncie, in the county of Delaware and State of Indiana, have invented certain new and useful Improvements in Filtering Plants for Waterworks and I do hereby declare the following to be aV full, clear, and exact description of the invention, suchas will enable others skilled in art to which it appertains to make and use the same.

` This invention relates to a new and useful improvement in filtering plants l for waterworks and it consists in the construction and arrangement of parts hereinafter described, and definitely pointed out in the claims.

My invention relates to improvements in parts in section.

filter-beds used in connectionwith city waterworks or where a large amount of water is to be iiltered daily; and the objects of my invention are to construct a filtering plant with large filter-beds arranged on different planes, passing the water through them by gravity, to provide means for heating the water as it passes from one bed to another, and, further, arranging the mechanism so that it can be easily and perfectly cleaned. -These and other objects not hereinbefore mentioned are accomplished by the construction illustrated in the accompanying drawings, whereinlike letters of reference indicate corresponding parts in the several views, and in which- Y Figurel is a top plan view of the filter-beds with the filtering material removed and the iiush-pipes omitted in section 2 and showing Fig. 2 is a vertical vlongitudinal section of Fig. l on the line :n Fig. 3 is a cross-section on the line ma: xx, Figi. Fig.A 4 is a cross-section on thev line :roca: 00x00, Fig. l, and Figs. 5, 6, and 7 are detail views.

In constructing my iilter plant I find it advisable to construct the basins double and arranged side by side, so that one can be iiushed and cleaned-while the other is'still in use. I have shown this construction in the drawings; but it is obvious that one set of filteringbasins would be sufficient in somecases.

In the drawings, A designates the side walls; A', the base, and A the dividing wall, separating the filtering-basins longitudinally.

`Serial No. 645,180. (No model.)

y In the drawings I have shown but two sets I of ltering-basins, although it is obvious that any number may be used. I have designated .these two sets as section l and section 2, respectively.

At the forward end of section 1 is placed a receiving-basin B, into which the water-sup- `ply is pumped through the supply-pipe B'. Between this basin B and section l is a vscreened opening B", through which the water passes over into the first iilter-bed. The base or oors A' of the filtering-basins incline downwardly toward the forward end thereof and are covered with soft drain-tiles C. These tiles or pipes are arranged in rows and are constructed in sections arranged end to end,

as plainly shownin Figs. 1 and 2.

Arranged above the soft tiles is a layer of broken soft sandstone G, as shown in Fig. 6. Above this is a layer of coarse gravel G', nut size. Above this is a layer of gravel G", pea size, and over this, forming the top layer, is a layer of fine lake-sand G". The different layers are separated by a perforated screen N. Y

At the rear end of section lis constructed an arch I, in which the rear ends of the draintiles empty, as shown in Fig. 2. The arch I is provided with manholes I', Figs. 2 and 4, :throughfwhich an operator with a hose can pass and flush and clean each row of tiles separately. The Ifiltering basins can be further flushed and cleaned by means of the l vertical perforated pipes I" and horizontal .perforated pipes I'", which are arranged within the basins. These perforated vpipes are connected with a high-pressure pipe-line H by means of the laterally-arranged pipes H', which are provided with valves H" for controlling each pipe. m'eans of ilushing and cleaning consisting of a nozzle M, provided with a perforated point M' and a valve M" for controlling the water passing through the nozzle. The nozzle is I provide an additional connected bya hose (not shown) to the branch pipe h. This perforated point can be inserted at will at different places in the filtering material and water forced through it similar to the operation of cleaning by the perforated pipes I" and I'". When the filtering-basins IOO Lan

are being flushed, the water can be drawn off through the drain-pipe J, as hereinafter described.

The water in the arch I is conducted therefrom by means of the pipes D, which extend down to near the bottom of the settling-basins E. rl`he settling-basins are provided with the salne kind of filtering material as the filtering-basins with the exception of the draintiles. The water rises up through this filtering material through the screens F.' into section 2. The water in passing from the arch to the settling-basin Eis heated by having steam forced in the pipes D. This is accomplished by means of the steam-pipes F, one for each pipe. The end 0f the pipes F are perforated at F', as shown in Fig. 5, and the pipe D is provided with an elbow D', so that the steam will more readily heat the water as it passes through the pipes. The pipes F are connected to a main steam-supply pipe F" and are provided with valves F', one for each pipe. The supply-pipe F" is provided with a valve F for shutting off either one of the basins.

The filtering material in the second section is the same as in section l and the water passes through the tiles Cinto the pipes D"", which lead to near the bottom of the second settling-basin E", which is also provided with filtering material, with the exception of the tiles. The water rises in this basin and passes into the clear-water basins O through the screens O'. The water is new thoroughly filtered and ready for use.

At the rear end of section 2 I show another way of cleaning the tiles, which consists of the cross-pipe D', which is connected to the high-pressure pipe II and is provided with a valve d for regulating the supply of water to the said pipe, and the branch pipes d', leading from the pipe D', the branch pipes being provided with the downwardly-extendin g portion d and horizontal portion d', extending into the tiles, there being one branch pipe foreach tile. IVhen water is turned into the pipe D', each tile will receive a stream and thoroughly wash and flush each tile.

D" designates valves for each branch pipe.

Extending upwardly from the downwardlyextending portions d" of the branch pipes d' are vent-pipes D"", which extend above the top of the filter and are controlled by the valves dm'. These pipes are left open as airvents and are closed when the basin is being flushed.

As before described, when the filtering-basins are being flushed the surplus water is drawn off through the pipe J. This pipe is connected to the forward end of sections l and 2 of the filtering-basins and also with the settling-basin E, as shown in Fig. 2. The connection is the same in all three places, anda description of one connection will suffice for all. The opening from the basin to the pipe J is controlled by a valve J', which has a stem J", extending above the filter, and a handwheel J on the stem. The valve is protected by a screen K', and a easing K surrounds and protects the valve-stem and also acts as a manhole if the valve needs repairing. Byhaving the base A' incline downwardly toward the forward end of the basin all the water will run toward the opening for the pipe J and all the water can naturally be drained off. The pipe J leads into a vat l, located beneath the second settling-basin E". The filtering material in the basin is prevented from falling into the vat by means of the screen e. The clear-waterbasin is also connected to the vatby means of the pipe J.

Located in the vat is a centrifugal pump L', which is adapted to empty the vat when the filtering plant is being flushed and cleaned, the water being forced up and out through the pipe L". The pump is operated by means of the rod L', which has a power-pulley L'' on its upper end, and the parts are protected by the casing L.

In the operation of the filtering plant the water is filtered by force of gravity downwardly through the filtering-basins and upwardly through the settling-basins, and after leaving the first filtering-basin it is thoroughly heated by means of the steam, which adds greatly to the filtering capacity of the plant. Of course it will be understood that the supply of water to be filtered is cut olf when the plant is being fiushed through the flush-pipes.

I am aware that many minor changes can be made in the construction and arrangement of parts without in the least departing from the nature and principles of my invention.

Having thus described my invention, I claim the following and desire to secure the same by Letters Patent:
